quarto vs Semgrep
A side-by-side editorial comparison of quarto and Semgrep — release velocity, themes, recent moves, and the top alternatives to consider.
quarto vs Semgrep: at a glance
What is quarto?
Quarto's editor extension is quietly becoming Positron-first while keeping VS Code parity.
This is the Quarto extension for VS Code and Positron — cell execution, preview and render, the visual editor, snippets, and the language-server plumbing that makes .qmd files behave like real code documents. The last several releases have pushed the editing experience toward parity with ordinary source files: diagnostics inside code cells, code symbols and cells in the outline, semantic highlighting, and clickable file links with autocompletion in _quarto.yml. A large share of every release is now Positron-specific work rather than generic VS Code support.
What is Semgrep?
Semgrep keeps spending releases on parser breadth and large-repo throughput, not new surface.
Ten consecutive releases have gone into the engine rather than the product. The recurring shape is a parser refresh (Solidity, Ruby, Dart), a scan-performance change, and a batch of correctness fixes for Pro analysis. Nothing in this window changes what a team buys Semgrep for; it changes how reliably a scan finishes on a large repository.

Quarto's editor extension is quietly becoming Positron-first while keeping VS Code parity.
◆ Current state
This is the Quarto extension for VS Code and Positron — cell execution, preview and render, the visual editor, snippets, and the language-server plumbing that makes .qmd files behave like real code documents. The last several releases have pushed the editing experience toward parity with ordinary source files: diagnostics inside code cells, code symbols and cells in the outline, semantic highlighting, and clickable file links with autocompletion in _quarto.yml. A large share of every release is now Positron-specific work rather than generic VS Code support.
◆ Where it's heading
Two patterns hold across releases. First, Positron is where new surface appears first — notebook editor commands, statement execution, runtime-aware language selection for new cells, and a bundled-CLI preference setting all landed as Positron features. Second, the extension is steadily stepping back from things dedicated tooling does better, giving up .typ files to Typst extensions and commenting out IPython magics in the virtual document so Ruff and Pyrefly stop flagging them. The multi-language story keeps widening, with Julia cells joining Python and R for in-editor execution.
◆ Prediction
Given how much recent work has been notebook-editor commands and .ipynb conversion, expect further consolidation of the notebook and .qmd paths behind shared commands rather than new authoring features.
Semgrep
5.0INFRA · APIS
Semgrep keeps spending releases on parser breadth and large-repo throughput, not new surface.
◆ Current state
Ten consecutive releases have gone into the engine rather than the product. The recurring shape is a parser refresh (Solidity, Ruby, Dart), a scan-performance change, and a batch of correctness fixes for Pro analysis. Nothing in this window changes what a team buys Semgrep for; it changes how reliably a scan finishes on a large repository.
◆ Where it's heading
The performance work is converging on one problem: very large monorepos. File targeting now batches path filtering across worker domains, rule parsing shards by bytes instead of worker count, and a new Pro memory policy lets a scan trade RAM for skipping on-disk caching. Running alongside it is a quieter thread of trust work, and the 1.173.0 fix for silently dropped targets belongs to it: a file whose path filtering failed appeared in neither the findings nor the skipped list, which is the kind of gap that undermines a scan report more than any missing rule.
◆ Prediction
Expect the parser-refresh-plus-throughput cadence to continue, with the memory policy and the dependency-path output likely graduating out of experimental once large-repo users report back on them.
